Gold particles are modified with surface-attached bis(beta-cyclodextrin)s bearing S-S bridges to give water-soluble cyclodextrin-modified gold nanoparticles, which are successfully used as recycling extractors for [60]fullerene.

We argue three-flavour neutrino mixing. We consider the neutrinos as Majorana particles and see how the neutrinoless double beta decay constrains the neutrino mixing angles. Our formulation is widely valid and is applied to the neutrino oscillation experiment.

The sensitivity of monolayers of Ilford L-4 nuclear emulsion to beta(-)-particles is approximately 0.20 grain per particle emitted for H(3), and 0.025 grain per particle for p(32). The sensitivity for thick layers is 1.3 grains per tritium beta(-)-particle emitted within the emulsion. In electron microscopic autoradiographs the maximum resolution is approximately 0.1 micron for H(3) and 0.3 mic...

The efficiency of the SIR ionization chamber versus photon energy has been obtained by an iterative method, starting from a few monoenergetic gamma-ray emitters. The relative standard uncertainty on the efficiency curve obtained is lower than 10(-2) above 65 keV. An efficiency curve for beta particles has been deduced in a similar manner, from measurements of (quasi-) pure beta emitters. The po...

Connexin36 (Cx36), a trans-membrane protein that forms gap junctions between insulin-secreting beta-cells in the Langerhans islets, contributes to the proper control of insulin secretion and beta-cell survival. Hypercholesterolemia and pro-atherogenic low density lipoproteins (LDL) contribute to beta-cell dysfunction and apoptosis in the context of Type 2 diabetes. We investigated the impact of...

Yeast cell wall matrix particles are composed entirely of beta-glucan and mannoprotein. Alkali-insoluble (1-->3)-beta-D-glucan was extracted from the yeast cell wall by an alkaline-acid method. IR spectra analysis showed that the product was chemically pure glucan, that is to say, it contained no other carbohydrates and proteins. So, the alkaline-acid method was ideal for extracting (1-->3)-bet...

The "many ensembles" method was proposed to investigate the influence of nuclear particles' post-scission emission on mass and charge distributions fission products. post scission approximation had been used; each these ensembles consists fragments after chains different lengths, both beta (±β) particles neutrons. theory allows one to
 find most probable two fragment clusters products stud...

In the event of an observation of neutrinoless double beta decay, a relevant question would be: what lepton number violating physics is responsible for the decay? The exchange of Majorana neutrinos and/or supersymmetric particles may contribute. We point out that measurements of supersymmetric signals at the LHC, including single slepton production, could be used to help bound some supersymmetr...
